The current supplied by a battery as a function of time is I(t) = (0.88 A) e^(-t*6 hr). What is the total number of electrons tr
Nimfa-mama [501]

Answer:

N = 1.2 \times 10^{23}

Explanation:

As we know that the current through the battery is given as

i = (0.88 A) e^{-t/6}

here from above equation we know that current will become zero when time elapsed is very large

so here we can say that charge will flow through the battery from t = 0 to t = infinite

now we have

q = \int i dt

q = \int (0.88 A) e^{-t/6} dt

q = 0.88\times -6(3600)\times (e^{-t/6})

q = -1.90 \times 10^{4} (0 - 1)

q = 1.90 \times 10^{4} C

As we know that

q = Ne

N = \frac{q}{e}

N = \frac{1.90 \times 10^4}{1.6 \times 10^{-19}}

N = 1.2 \times 10^{23}

How long will it take a person walking at 2.1 m/s to travel 13 m?
MrRissso [65]

Answer:

I gonna give you the number so but you need to round 6.19047619048

Explanation:

  • This is a speed formula so you would use the formula speed=distance/time
  • You need to rearrange it to time=distance/speed
  • So you need to divide 13m by 2.1 m/s

What are the forces that act on the ball pushed on the floor​?<br><br>Plss answer
vaieri [72.5K]

Explanation:

The ball, for example, will feel gravity pulling it downward and the ground pushing it upward in the direction it is rolling. (Add this if the ball is rolling on the floor.) Friction is the force that causes the ball to slow down because it acts in the opposite direction that it is moving.
